# Problem sets and exams

Almost every other Thursday, there will be an exam during the last hour of the class period, closely based on an associated problem set. (However, there is no exam in the first week of the course or on Thanksgiving, and there is an additional final exam on Thursday in the last week.) Unless otherwise specified, all problems are from the 10th Edition of Algebra & Trigonometry written by Sullivan and published by Prentice-Hall (Pearson).
